Fuse location for turn indicators E53

[AW8]

Trying to help a member out on other board who has facelift E53 with both headlamp unit located & adjacent side panel turn indicators not working, (one side only), rear seems fine on same side.

I have advised checking by swapping bulbs, (maybe a coincidence), in first instance but I cant advise on how to check fuse/relay.

I checked my prefacelift & nothing obvious in trunk or glove box.

Seems a daft & silly query but searched these fine boards without finding anything as of yet.

I found this link but am not embarrased to admit it means nothing to me......I do some work, (& have changed ther front indicator bulbs before), on my car but I'm not an auto electric expert.

Responses appreciated as to fuse/relay location & any other advice.
